Example Challenges: VENC_SDCard_ThreadX

[Woobie]

Hello! I am using the following:

Using STM IDE: Version: 2.1.1
Build: 28236_20260312_0043 (UTC)

Working on the example for the STM32N6570-DK "VENC_SDCard_ThreadX", it seems to freeze after a few frames and loses link with debugger. Appreciate any thoughts on what could be causing this! I am using a 32GB micro-SD. I have isolated that the issue seems to be in app_filex.c inside of the function: 

VENC_FileX_write((CHAR*)data, (LONG)size).

I am thinking there is a conflict between write speeds to the SD card but would be grateful for any insight from the group!

Thank you!

Hi @Woobie 

I have extensively tested the VENC_SDCard_ThreadX application using EWARM and cannot reproduce the freeze or debugger disconnection you reported. The application runs stably without issues in my testing environment. 

Upon reviewing the code, I assume that the VENC_FileX_write() function lacks robust error handling: which could mask SD card write failures in corner cases. However, this has not resulted in functional defects or freezes in my testing to be escalated.

Hi @FBL!

Thanks so much for looking into this! I am using the STM IDE Version: 2.1.1 and the example code under the STM32CubeIDE not EWARM. Not sure if this small difference could be the reason the issue is not reproduced. Appreciate your help!
